Inkjet cartridge for inkjet recording apparatus, inkjet recording apparatus and method of supplying ink

Abstract

An ink cartridge for inkjet recording apparatus including: an ink pack including an ink feeding section of thermoplastic resin; a bag-like ink accommodation section of multilayer thermoplastic film materials; an ink filled in said ink pack; a positioning control member for controlling a position of said ink feeding section; and an outer box for accommodating said ink pack, wherein said ink feeding section comprises a hollow cylindrical ink feeding tube including: a joint section for jointing with said ink accommodation section; a positioning control means accommodated in said positioning control member; a first opening through which an ink supply means in said inkjet recording apparatus can be inserted and pulled out; a second opening for supplying said ink to said inkjet recording apparatus from said ink accommodation section via said first opening; and a cover for opening said second opening by inserting said ink supply means and for closing said second opening by pulling out said ink supply means, and wherein said ink is the UV curing type with a viscosity of 0.005 through 0.1 Pa·s.

1 . An ink cartridge for inkjet recording apparatus comprising: 
 an ink pack including an ink feeding section of thermoplastic resin; a bag-like ink accommodation section of multilayer thermoplastic film materials; an ink filled in said ink pack; a positioning control member for controlling a position of said ink feeding section; and an outer box for accommodating said ink pack,    wherein said ink feeding section comprises a hollow cylindrical ink feeding tube including: a joint section for jointing with said ink accommodation section; a positioning control means accommodated in said positioning control member; a first opening through which an ink supply means in said inkjet recording apparatus can be inserted and pulled out; a second opening for supplying said ink to said inkjet recording apparatus from said ink accommodation section via said first opening; and a cover for opening said second opening by inserting said ink supply means and for closing said second opening by pulling out said ink supply means, and wherein said ink is the UV curing type with a viscosity of 0.005 through 0.1 Pa·s.    
   
   
       2 . The ink cartridge for inkjet recording apparatus of  claim 1 , wherein inside of said cover of ink cartridge for inkjet recording apparatus comprises an engagement section capable of engaging with and disengaging from said ink supply means.  
   
   
       3 . The ink cartridge for inkjet recording apparatus of  claim 1 , wherein said ink pack is protected by protective members.  
   
   
       4 . An inkjet recording apparatus comprising: an ink supply means including an insertion member capable of being inserted and pulled out through said first opening in the ink cartridge for inkjet recording apparatus of  claim 1 , wherein said insertion member comprises a hollow cylindrical ink supply tube including at an end portion thereof an engagement section for opening and closing said cover, an ink supply port, and an ink leakage prevention member, and wherein said ink is the UV curing type with a viscosity of 0.005 through 0.1 Pa·s; an area of said ink supply port being 1 through 20 mm 2 ; an inner diameter of said ink supply tube being 4 through 8 mm.  
   
   
       5 . The inkjet recording apparatus of  claim 4 , wherein said insertion member comprises a cleaning member for cleaning said insertion member.  
   
   
       6 . The inkjet recording apparatus of  claim 4 , wherein said ink pack is protected by protective members.  
   
   
       7 . A method of supplying ink to the inkjet recording apparatus by inserting the insertion member in the ink supply means into said ink feeding section from the ink cartridge for inkjet recoding apparatus of  claim 1 , wherein said insertion member comprises a hollow cylindrical ink supply tube including at an end portion thereof an engagement section for opening and closing the cover, an ink supply hole, and an ink leakage prevention member; and wherein said ink is the UV curing type with a viscosity of 0.005 through 0.1 Pa·s; the area of said ink supply port being 1 through 20 mm 2 ; the inner diameter of said ink supply tube being 4 through 8 mm.  
   
   
       8 . The method of supplying ink of  claim 7 , wherein said insertion member can be inserted and pulled-out through the first opening via the cleaning means.  
   
   
       9 . The method of supplying ink of  claim 7 , wherein said ink pack is protected by the protecting members.
